Im only a month in and my pain is more shooting and deep aching and crushing pain. I am only just starting to get mild burning pain in my fingers and a little sensitivity. I have rsd in my left arm and hand, Im also only just starting to get a rash as well. Bacause of this i really felt at first that i didnt qualify for RSD/CRPS. But end of the day I have all of the other symptoms and more developing. I also find that when the swelling is up i get less pain and more of a numb feeling so perhaps its the same with you? Even though the swelling isnt great i will admit i prefer it because the pain is so much better.
I hope your still pain free, you really are lucky.
